MCR

MCR (Microconcrete) is cementitious, non-shrink, pourable, high strength for structure repair with high precision concrete. It is specially designed for restoring horizontal concrete surfaces damaged through concrete spalling and mechanical causes. It is recommended for thickness from 20 to 100 mm. It is suitable for various structural strengthening measures such as encasement build-ups, jacketing etc.

ASTM C 109 and ASTM C 230
Flowable mortar eliminates Honeycombing
Develops high initial and final strength
Gaseous expansion system compensates for shrinkage & settlement in the plastic state
Excellent resistance to moisture ingress
Easy to clean and can be pumped in restricted areas
No compaction required
Contain no chloride

Suitable for repairing of damaged reinforced concrete elements like slabs, beams & columns
Suitable for repairs of concrete wall
Can be repaired such concrete elements where access is restricted and compaction not possible
Can be used for jacketing of RCC columns to increase load bearing capacity
Suitable for pumping & pouring at restricted areas also

Any kind of internal and external concrete repairs
Concrete structures like columns, beams, floors, walls and other repairs
